In a more general scheme we construct a three-fold covering of ${U} (n)$ and consider for the case $n=2$ several representations which are used in the construction of a model of the electroweak interactions in a subsequent paper.RevTex, 5 pagesHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
